Illinois Application February 25, 1935, Serial-No. 7,960

4 Claims.

This invention relates to building construction,

' and has reference more particularly to ribbed metal sheets or decks faced with fibrous material suitable for thermal and sound control.

In the use of metallic roof and floor decks,

such as that described in Patent No. 1,900,721,

mit easy erection and so as to permit the insertion.

of the fibrous material; also to improve building construction in other respects hereinafter specified and claimed.

Reference is to be had to the accompanying drawing forming a part of this specification, in-

which Fig. 1 is a perspective sectional view of our improved form of building construction,

Fig'. 2 is a transverse sectional elevation through the improved building structure,

Fig. 3 is a perspective sectional view through the structure showing the manner of attachment to supporting beams,

Fig. 4 is a perspective sectional elevation showing the manner of attaching one deck to the adjoining deck, and

Fig. 5 is a perspective sectional view showing a modified form of attaching the decks to supporting beams.

Referring to the drawing by numerals, beams I may conveniently be in the form of channel sections having outstanding upper flanges I I and lower flanges I2. Metal decks I3 are in elongated form and are provided with downstanding integral ribs I 4 extending longitudinally of the deck intermediate the longitudinal edges thereof. One longitudinal edge of each deck is formed into an upwardly opening channel I5, and the opposite edge is provided with a downstanding flange I6 adapted to be telescopically received in the chan- I of the adjacent deck. Reinforcing ribs I! are formed'in the deck plates I3, said ribs extending from one end of the deck to a point somewhat short of the other end. The bottoms of the ribs I4 and channels I5 are adapted to rest upon the beam flanges I I to form a roof or floor. In the case of using the decks for a roof, a bituminous mastic I8 is mopped hot onto the upper surface of the decks and insulating fiber boards III are caused to adhere to thejmastic. -A weatherprotecting layer of asphalt roofing 20 is then. applied to the fiber boards I9 by mopping in place with a hot bituminous mast An elongated strip of metal 2| is secured to the bottom of each of the ribs I4 and the channel I5, as by spotwelding. Fiber board strips 22 are supported at their outer edges on the strips 2|, said boards being preferably of wood or otherflbers and being of a porous nature suitable for the acoustical absorption of sound and for thermal insulation. The boards 22 are held firmly in position to prevent lifting upon upward pressure on said boards when the lower surfaces are cleaned, by flanges 23 which are struck out from the walls of ribs I4. The ends of adjacent roof decks telescope together as seen in Fig. 1, and the strips 2I are shorter than said decks to permit said telescoping. At the points where the ribs II and strips 2| of the decks rest upon the beam flanges I I, (Fig. 3) said strips 2| are cut on diagonal lines with shears or other suitable tool, to form flanges 24 and 25. The flange 24 is bent downwardly against the web of beam Ill and flange 25 is bent around the beam flange II so as to firmly anchor said decksto the beams Ill. The adjacent decks are secured together one to the other, by means of clips 26 which follow the contour of channels I5 and flanges I6, said clips having a flange 21 which is bent down on top of a deck to lock said decks together.

Instead of the anchoring device shown in Fig. 3,

' a modified form of clip 28 (Fig. 5) may be used.

This clip has fingers or flanges 29 which are bent around the beam flanges II, and opposed flanges 30 which lie in abutting relation against the web of channel beam It, thus anchoring the clip to said beam. The clip 28 also has a return bent flange 3| which engages the upstanding flange of channel I5.

The roof deck above described presents a simple structure for either roofs or floors having combined structural strength, sound absorption and thermal insulation. The decks are firmly anchored to the supporting beams. The roof presents a neat, finished appearance from below.

We would state in conclusion that while the illustrated examples constitute practical embodimentsvof our invention, we do not wish to limit ourselves precisely to these details, since manifestly, the same may be considerably varied without departing from the spirit of the invention as defined in the appended claims.

Having thus described our invention we claim as new and desire to secure by Letters Patent:-

I. In a building construction, a composite building deck comprising a metallic sheet having depending integral ribs, sheets of fibrous material between said ribs, fiat strips 01' metal secured to the bottoms of said ribs and supporting the outer edges oi said'fibrous sheets, and fianges struck out from said ribs and engaging the top faces of said fibrous sheets to prevent said fibrous sheets.

from lilting upon the application oiupward pressure on said fibrous sheets. 2. In a building construction, a composite building deck comprising a metallic sheet having depending, integral ribs, sheets of fibrous material between said ribs, fiat strips of metal secured to the bottoms of said ribs and supporting the longitudlhal edges oi said fibrous sheets, flanged beams supporting said deck, and flanges formed from said strips of metal, said flanges engaging said beam flanges to secure said decks to said 3. In a building construction, a composite building deck comprising a metallic sheet having depending, integral ribs, sheets of fibrous material 1 between said ribs, strips of metal secured to the bottoms of said ribs and supporting the longitudinal edges 01' said fibrous sheets, flange struck out from said ribs and forming openings in said ribs, said fianges engaging the top faces of said fibrous sheets to prevent said fibrous sheets from lii'ting upon the application oi. upward pressure on said fibrous sheets, and a weather protecting layer above said metallic sheet and closing said rib openings.

4. In a sound and thermal insulated roof deck unit, a metallic sheet having depending, integral, longitudinal ribs, sheets of fibrous material between said ribs, and separate fiat strips of metal secured to the bottoms of said ribs, the outstanding edges 01' said strips supporting the longitudinal edges of said fibrous sheets.
